java - Hibernate eager loading not fetching all child rows -

-

hibernate version 4.3.10

i have parent/child relationship described in example. there occasions when expect 1 row returned when querying provider. in case, limit criteria calling setmaxresults method 1.

dump of sql revealed hibernate makes outer join calls ends returning more 1 row, because of limit set on criteria, first child row read database. 

    @entity     @table(name = "f_provider")     public class provider {         @onetomany(cascade = cascadetype.all, mappedby = "provider", orphanremoval = true, fetch = fetchtype.eager)         private final set<credentialfielddefinition> credentialfielddefinitionlist; }  @entity @table(name = "f_cred_fields", uniqueconstraints = { @uniqueconstraint(columnnames = { "name", "provider_id" }) }) public class credentialfielddefinition { @manytoone(targetentity = provider.class, optional = false)     @joincolumn(name = "provider_id", nullable = false, unique = false)     private provider provider; }

how convince return me full child set when reading row?

you can try using subselect fetch mode:

@onetomany(cascade = cascadetype.all, mappedby = "provider", orphanremoval = true, fetch = fetchtype.eager) @fetch(fetchmode.subselect) private final set<credentialfielddefinition> credentialfielddefinitionlist;

this way credentialfielddefinitionlist initialized in separate query.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
